Slovenia’s state-of-the-art coal-fired plant decides for intelligent on-load boiler cleaning
Wesel/Germany, September 2011
EPC-contractor ALSTOM Power Systems GmbH, Stuttgart/Germany awarded a contract to Clyde Bergemann as the sole supplier of the on-load boiler cleaning solution for unit 6 of the Šoštanj coal-fired power plant in Slovenia. With a net efficiency of 43 %, the new 1x600 MW ultra supercritical tower-type unit, whose construction is in progress, will make this station one of the most efficient and advanced in Slovenia.
According to the specific cleaning requirements of the different boiler areas, e.g. furnace, superheater, economiser, air heater and DeNOx, the overall 128 sootblowers consist of the series water cannon, long retractable, helical, rake and rotating element. The furnace will be equipped additionally with the optimisation system SMART Furnace-FACOS. This system uses sensors to detect the position and intensity of slagging in the furnace area. This data will be linked with the current performance data of the steam generator to decide upon stored algorithms which cleaning action needs to be done and at what intensity. SMART Furnace-FACOS not only regards the level of slagging but also the influence of the imminent cleaning operation on boiler performance. Clyde Bergemann carries out engineering, installation and commissioning.
Termoelektrarna Šoštanj d.o.o. operates the station. The coal is supplied by the near-by lignite mine Premogovnik Velenje. When operational in 2014, unit 6 replaces the older units which have been brought on line from 1956 to 1977.
